CORRUGATED STRUCTURE FOR RAILWAY CARS.

Application filed October 23, 1925.

My invention relates to the construction of railway cars having partsformed of metallic plates which are subjected to lateral, buckling andsometimes torsional stresses. Said parts are made of one or moremetallic plates or panels formed with vertical or horizontalcorrugations or other integral stiffening or bracing means to resi tsuch stresses. While eiforts are made to block the lading in car, theshocks caused by the heavy locomotives. the emergency air brake and theclassification hump tear the lading away from its moorings and throw itagainst the end of the car, the lateral weaving of the car throws itagainst the side of the car, and the impact throws it against the bottomof the car. My invention is adaptable to several parts of a railway ear,such as side doors, side walls, floor sheets (sloping or otherwise),hopper doors. roof sheets, etc, but it is especially adaptable for useas the end wall of a railway car and is also adaptable to box, gondolaor other types of cars.

One ofthe objects of the invention is to provide metallic parts of arailway car which have great strength to resist the torsional andweaving stresses which exist in a railway car when moving in service.These stresses are caused and superstructure when the train is suddenlystopped; rough or uneven track; the superelevation of the track oncurves; the lat.- eral inertia in rounding curves; eccentric thrust dueto the lading being secured to one side of the car; the cars beingcornered; the use of push pole pockets, etc. Such stresses rack anddistort the superstructure which decreases the life of the car, and alsocauses the car to leak grain, sand an other such material. Furthermore,such stresses cause leaky roofs and leaky and inoperative side and enddoors.

The tendency of an all metal end wall to bulge is resisted partially bythe corrugations. stiffening members or whatever means have beenprovided to transmit such stresses to the side wall or frame-members ofthe ear. Such tendency is also resisted by the corner post of the caracting as a vertical beam supported at its top and bottom and sustaininga horizontal load; in other words, the bulging of the end would pull theopposite corner posts toward each other. This bulging also tends to pullthe end (or side) plate downwardly and the end (or side) sill upby theinertia of the roof Serial No. 64,466.

wardly. Another object of the invention is to reinforce the framemembers against thrust perpendicular to their length by means forming apart of a corrugated or otherwise reinforced metallic end wall.

Since the corrugated metallic wall is braced against buckling it initself has con siderable resistance to the lateral stresses but the wallmust be well secured to the frame members, (post, sill and plate) inorder to secure the co-operation between these frame members and betweenthe metallic wall and the frame members. Another object of the inventionis to obtain an improved method of securing a corrugated metallic wallto the frame members of the car.

A part of the metallic plate is pressed to form a panel 14 surrounded byan integral part of the plate positioned angularly to the plane of thepanel. If this surrounding partconstitutes the edges of the plate thenit would technically be called a flange. However, it may be providedwith a laterally extending part- (or flange 28-27) so that thesurrounding part would then technically be called a web. This laterallyextending part is not an element of the broader claims of thisapplication, therefore. to avoid the use of two different words todesignate the same element. in different claims, the word web is used todesignate that part of the plate surrounding the panel and positioned atan angle thereto whether it constitutes the edges of the plate or not.

It has been proposed to press the central portion of a metallic plate(or plates) so as to form a continuous Web or flange surrounding a paneland to reinforce this panel by horizontal corrugations or other integralreinforcements which traverse the panel and terminate adjacenttheopposite portions of lll) (all

the web or flange. In such an arrangmuent the load upon the horizontalcorrugations is transmitted to the continuous web or flange only throughthe intermediate means of the flat portion of the plate lying betweenthe end of the horizontal corrugations and continuous web or flange. Ithas also been pro posed to press the central portion of a metallic plate(or plates) so as to form a web or flange (supposedly) surrounding apanel and to reinforce this panel by horizontal corrugations or otherintegral reinforcements which are the same depth as the web or flangewhere they merge into it. In such an arrangen'ient the web or flange, asa beam,

is destroyed. In my construction the trans verse corrugations destroyonly a part ol the value of the web, leaving a remaining portion whichextends continuously around the panel to receive the stresses from thehorizontal corrugations and to function as a beam and a stiffener. Suchstresses are transmitted direct y to the remaining portion of the web. 7

That portion of the web between the corrugations serves as an excellentplace for an attaching bolt or rivet because a bolt or rivet sopositioned then also restrains the corrugations against deflection.Further more, a bolt or rivet so positioned prevents the web frombuckling as it has a tendency to do when acting as a beam.

, In the drawings the usual parts of the car are shown such as the endsill 1; end plate 2; side sill 3; side plate 4; side girth 5; cornerpost 6; side lining 7; side sheathing 8 end lining 9 and end fascia 10.

In my construction the central portion of the metallic plate 11 (orplates 1112) is pressed to form a continuous web 1316 surrounding apanel 14. This panel 14- is reinforced with corrugations or integralribs, some of which 70 traverse the panel (in the preferred form) andmerge into a part of the opposite portions 16 of the continuous web,while other shorter corrugations 74 traverse a partof the panel andmerge into the panel preferably adjacent the opposite portions 72.73 ofthe web. The two types of corrugations 7074l may be positionedalternately but their relative number and position may be diversified tosuit conditions. The shorter corrugations Tel are preferablyshallowerthan the longer corrugations 70. The remaining portion 26 ofthe continuous web extends continuously and uninterruptedly on three (orpreferably four) sides of the wall. This Web receives the load from thecorrugations and formsa beam or stiffener to prevent bulging intransmitting the load from the corrugations to the frame of the car.These remaining portions of the vertical parts 16 of the continuous webare prevented from buckling or deflecting by being formed integral withthe horizontal parts 13 of the continuous web preferably by radialportions 17). The web preferably lies against the adjacent frame member,such as corner post 6, end sill 1 or end plate 2 and is secured theretoby bolts 18 which are preferably positioned between the corrugations.Other means 19 are provided to secure the plate to the frame memberwhich are preferably positioned in alignment with the corrugationsi'These two means may be used jointly or severally. The plate is securedto the end sill l. by bolts 202l and to the end plate by bolts 2223.

Figs. 9 and 10 show an enlarged section of the corner post andillustrates the relation of the web, the corrugations and the attachingbolts 18 and 1.9.

\Vhile I have shown and described the corrugations positionedhorizontally, it is understood that the corrugations may extendvertically or otherwise, and still come within the scope of theinvention, and, fur thermore, while I have described and claimed thewall made of a plate, it is understood 7 that .it may be made of one ormore united plates and still come within the scope of the invention.
